Infection only please. Or at least something that works similarly. I'm working on Zombie Island, and version 3 will be out soon. (Version 2 was not released on forgehub because of buggy gameplay.) But besides that, I haven't had any ideas on what to do for my new maps.
how about this... theres a town and the zombies are trapped for 2 minutes or something, and the humans have to go to buildings to barricade themselves in before the zombies come...
